SWITCH MECHANISM.

To (LZZ'UJILO/ll lid mm concern: 1

Be it known t at I, Nan. E. SALSIOH, a citizen oi the United States,and, resident of Bethlehem, county of Lehigh, State of Pennsylvania,have invented certain new and useful Improvements in Switch Mechanism,of which the following is a specilication.

The present invention relates to switch stands and more particularly tomeans to actuate the signal usually employed to indicate the position ofthe switch.

Signals of the usual type associated 'Wltll switch stands are movedthrough an angle of 90 when the switch is thrown. Some switch throwingmechanisms however do not have any member which moves through exactly90, and the present invention is directed to provision of means foractuating a signal employed. with a mechanism oi. the latter type.

The objects and features of novelty of the invention will be apparentfrom the description taken in connection with the drawings, in which:

Figure 1 is a top plan view of a switch stand having a signal disposedand actuated according to the present invention;

Fig. 2 is a view similar to Fig. 1 illustratin g the positions of theparts at the other end of the throw of the switch, and

Fig. 3 is a sectional elevation taken substantially on the broken line33 of Fig. 1.

Referring to the drawings the switch stand with which the presentinvention is shown is that disclosed in my Patent No. 1,303,967 grantedMay 20, 1919. this switch stand comprises a base 10 adapted to besecured to a pair of adjacent ties 1]. and having an upstanding post 12carrying a rotatable member 13. This rotatable member has two arms, oneof which, indicated at 14, is connected to the switch by a rod 15. Theother arm, indicated at 16, is formed witha curved slot 17 in whichoperates the block 18 pivotally carried by the hand operating lever 19.In throwing the switch the hand lever 19 is moved from the positionshown in Fig. 1. to that shown in Fig. 2, that is, through an angle ofsubstantially 180. This movement, through the block and slot connection,turns the member 13 through an angle a (Fig. 1). It will be observedthat this angle a. is less Specification of Letters Patent.

than 90 and hence the signal cannot be di- .rie's the signal, this postbeing rotatably mounted in the bore 21 and held against downwardmovement by means such as the collar 23. Post 22 projects slightly belowthe arm 20 and is formed with a transverse aperture 2 1. A link 25 isslidably disposed in the aperture 24: and has an end 26 bent downwardand fitted in a recess 27 in the base 10 of the switch stand. As shownthe recess 27 is intermediate the axes of the signal and the member 18.Hence as the arm 20 swings through the angle a, the signal will turnthrough a different angle indicated. at b, the location of the recess 27being such that the signal will turn through substantially 90 in thepresent embodiment.

It will be observed that the above described means provides a verysimple mechanism for turning a signal, where it is not possible toobtain the desired movement by directly securing the signal to a memberof the switch stand. Furthermore, the link 25 is disposed. under the arm20 and is always covered thereby, thus protecting the link from injury.If desired the post 22 may be provided. with an. aperture 28 disposed atright angles to the aperture 24 so that the post may be interchangeablyused with a switch stand on either side of the track.

Although a specific embodiment of the invention has been described indetail, it is to be understood that the invention is not thus limitedbut includes modifications and changes which come within the scope ofthe appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. The combination with a switch stand, of an arm pivotally mounted atone end and having a rotatably mounted signal at the other, meansconnecting said arm and the switch stand mechanism whereby the arm isswung when the switch is thrown, and means operated by the swinging ofsaid arm to turn the signal.

2. The-*combination with a switch stand, of a member pivotally mountedthereon, a signal rotatably carried by said member eccentric to itspivot, means to turn the member when the switch is thrown, and meansoperated by the swinging of said member to turn the signal.

3. The combination with a switch, of a pivotally mounted member, asignal rotatably carried by said member eccentric to its pivot, means toturn the member when the switch is thrown, and means operated by theswinging of said member to turn the signal. at. The combination with aswitch stand having a pivoted member adapted to be turned when throwingthe switch; of an arm rotatable with said member, a signal pivoted onsaid arm eccentric to the pivot of said member, and a link pivotedintermediate the member and signal pivots and slidingly engaging thesignal, whereby the signal is rotated when the member is turned.

'5. The combination with a switch stand having a pivoted member adaptedto be turned when throwing, the switch; of an arm rotatable with saidmember, a signal post pivoted on said arm eccentric to the pivot of saidmember, and a link disposed under said arm pivoted to the standintermediate the member and signal pivots and slidingly engaging saidpost, whereby the signal is rotated when the member is turned.

6. In a switch stand having a member rotatable through an angle of lessthan 90 when the switch is thrown, a signal rotata; bly carried by saidmember, and means actuated by the movement of said member in throwingthe switch to turn the signal through substantially 90.

7. In a switch stand having a switch operating member pivoted to swingthrough a definite angle when the switch is thrown, a signal rotatablycarried by said member, and means actuated by the movement of saidmember in throwing the switch to turn the signal through a differentangle than the member.

In testimony whereof I affix my signature.
